2022 Jeep Grand Cherokee

Dear NHTSA, I am writing to report a serious concern regarding my vehicle’s sunroof drainage system. Recently, a professional repair shop confirmed that the sunroof drain hose had become disconnected behind the firewall. As a result, water leaked into the interior of the vehicle and caused extensive corrosion to major electrical components, including the wiring harness and fuse box located behind the dashboard. The shop provided an estimate of approximately $5,000 to repair the damage, all directly related to water intrusion from this detached hose. At no point was I ever informed—by the manufacturer, dealership, or in the owner’s manual—that the sunroof drain hose required any type of regular maintenance or inspection. This lack of guidance left me completely unaware of any risk of disconnection or the potential for serious water damage as a result. I am also aware that there was a class-action lawsuit a few years ago related to defective sunroof drainage systems in certain vehicle models, which caused similar issues. Given the similarity in symptoms and consequences, I believe this may point to a broader pattern or design flaw that puts other vehicle owners at risk as well. I respectfully ask that NHTSA investigate this matter as a potential safety or design defect. I am happy to provide photos, shop documentation, or additional details upon request. Thank you for your time and consideration. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Randomly, and without warning, the instruments, gauges, and displays will switch into a language I do not speak or understand (Italian). Coinciding with the switch to Italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable), pedestrian emergency brake (peb) lamp or forward collision warning (fcw) lamp turns on with no way to re-enable safety features, units of measurement including speed, temperature, etc. all change, and many other random settings change as well. ***This is clearly a dangerous situation because of all the functions and gauges that change, and the fact it is difficult if not impossible to recover from this due to the language of the setting menus, and the complexity of discovering and navigating through all these changes. I have taken it to the dealer four times. They provide fix that last a week, then say there is nothing they can do and to wait for a possible software update, but none has come and it has been almost a year. When this happens, even if one is able to wade through all the settings menus and change setting back, some items cannot be reset (like the FCA off lamp). According to various Jeep owner forums, some dealers have been able to reset something and temporarily correct the issue, but they charge for this service, and the issue returns randomly again. Here is an example forum discussion, indicating many if not all vehicles are affected: [XXX] Because this is dangerous (for settings/gauges/units to no longer be useful while driving), and it occurs randomly, I strongly believe this issue should be a manufacturer recall. I am available for any needs and have all paperwork from the four Jeep visits. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In January work related to recall 95B was performed on the Jeep. The next day the issues started with a warning light indicating the Hybrid System needed service. The Jeep has been in repair for this issue 6 times and over 56 days with no resolution. It is currently in for repair. A buy back request was made but both FCA and the arbitrators indicate it is not a safety concern. There are safety concerns related to the Warning light as it appears to impact electrical communications in the vehicle. Repair notes indicate the communication issues. Also, power steering has stopped working and the engine has died while driving causing a rapid deceleration. Multiple users are reporting the same issues or additional impact related to the Hybrid warning light that started after 95B work.

Last week I was driving 70MPH on the highway when suddenly I got the red wrench icon with the message "Service Hybrid Electrical System" on the dashboard. After about 7 seconds I then got a "Put foot on brake and press start" message on the screen - while still going 70MPH on the highway. At that point the car died. I had no power - the accelerator pedal did nothing. Luckily, I was able to pull over to the shoulder and stop. Then I did what it said and pressed the brake + start button. The car came back to life, but I didn't have the full hybrid system - I only had gas - the car was not using any electrical power as the battery level remained constant and did not drop as I drove. I continued for another 20 minutes where I stopped for lunch. When I returned to the car it started up normally and continued to run normally after that. This is the 3rd of 4th time the red wrench icon with the Service Hybrid system warning coming up, but on the previous times the message went away after about 5 seconds and the car drove normally. This is the only time that it caused the car to completely die on my while on the highway. Apparently, this has been happening to a *lot* of people after Jeep issued a software update to address the 95b recall last year. Many owners are now afraid to drive their Jeep 4xe for fear of it suddenly dying on the highway at high speeds.

I am filing a complaint regarding repeated and dangerous safety failures with my 2022 Jeep Grand Cherokee Overland 4xe, which I purchased as a brand-new vehicle on February 22, 2025. The most critical issue is that the vehicle has shut off on two separate occasions—once while in motion driving up a hill and once during a suspension height adjustment while stopped. In both cases, the engine powered down unexpectedly, a red wrench and lightning bolt warning appeared, and the vehicle shifted into park on its own. I was unable to restart the vehicle immediately, creating a severe hazard. These shutdowns were preceded or followed by system warnings including “Electric Mode Unavailable – Service Required,” “Active Driving Assist Unavailable,” “Night Vision Unavailable,” “Traffic Sign Assist Unavailable,” and “Tire Pressure Monitoring Unavailable.” These alerts began appearing within weeks of purchase and have persisted intermittently, sometimes alongside performance issues such as sudden jolts at highway speed. The CDJR dealership in Northern California and various manufacturer (Jeep/Stellantis) technical advisors have inspected the vehicle multiple times. A software defect has been identified and confirmed by Jeep, but no fix is available. A Technical Service Bulletin 08-003-25 dated January 8, 2025—before I purchased the vehicle—acknowledges this issue. Despite this, the vehicle was sold to me, and I was sent home with it multiple times even after reporting these failures. The dealership and manufacturer technical advisors now consider the vehicle unsafe to operate and will not return it until a software update is released. The vehicle is currently at the dealership and available for inspection upon request. Supporting documentation including service records, warning light photos, and communications with Jeep Customer Care and the dealership, can be provided. I urge the agency to investigate this matter due to the confirmed safety risk and lack of timely resolution.

What component or system failed or malfunctioned, and is it available for inspection upon request? When driving down a busy road, the car completely stalled with loss of power steering, unable to accelerate or brake, power completely lost in car with all safety lights illuminated on the dashboard. Eventually brakes returned, able to stop car. Unable to restart and loss of power for windows. After several attempts, restarted car with warning lights still present- moved to side of Road. Currently at dealer for inspection- stated that problem was "digital crash input code failure" and that there is not a fix for this at this time. How was your safety or the safety of others put at risk? Car stalled with complete loss of control in the middle of traffic, while accelerating at approximately 15-25 mph. This could have caused an accident, but luckily did not. However, car was stalled in traffic for about 30 mins and unable to move car at all- blocking traffic on busy street. If happened on highway, could have been much worse and also had the potential to cause an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem was confirmed by dealer, and said that there is "no fix". According to them, all recalls have been fixed in this vehicle prior to incident and should have fixed this problem by replacing the battery. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Vehicle has been inspected by both dealership service and Chrysler/ Stellantis engineers. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was 1 warning light message about "EV system hybrid control" needs service, but disappeared after 30 seconds and this appeared about 1 week prior to incident.

After software updates the language switches (English to Italian). The cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable), the forward collision warning (fcw) lamp turns on stating that it is not working, with no way to fix, units of measurement including speed, temperature, etc. all change, and many other random settings change as well. The head unit will randomly restart.

- I received a "service hybrid system" light while driving (it only appeared for a split second and went away) and I took it to the dealership for troubleshooting. The dealership found a stored code of B273C-00. They contacted their Jeep engineers who have not been forthcoming as to what the issue is, but said the vehicle is not safe to drive, so I am not allowed to have the vehicle back (the same dealership has a 2nd Grand Cherokee 4xe with the same issue). Both vehicles are currently at the dealership and should be available for inspection. From my online research it seems to be tied to the vehicle's crash sensor and high voltage cable harness. There are also numerous other owners in online forums discussing the same issue with their Jeeps (Grand Cherokees and Wranglers). -As Jeep engineers are not allowing myself or others to drive their vehicle with this code, they obviously consider it a safety issue. The scary thing to me is, that had I not happen to see that quick flash of the "service hybrid light" I would be driving this unsafe vehicle without knowing it, as it did not turn on the check engine light, so I had no idea there was a stored code until the dealer checked it out. That means there are probably thousands of folks driving around at risk without even know there is a safety issue. -This issue has apparently been going on for months, as the other Jeep at my dealership has there for months now.
